Vertical Overflow and Cells with Constrained Height #737
Description
In some cases, text can be very long within a cell and a user may wish to constrain the height of the cell.
This currently requires a css= workaround. It would be nice if it didn't.
From the docs, this is:
dash_table.DataTable(
style_data={
'whiteSpace': 'normal',
},
data=df_moby_dick.to_dict('records'),
columns=[{'id': c, 'name': c} for c in df_moby_dick.columns],
css=[{
'selector': '.dash-spreadsheet td div',
'rule': '''
line-height: 15px;
max-height: 30px; min-height: 30px; height: 30px;
display: block;
overflow-y: hidden;
'''
}],
tooltip_data=[
{
column: {'value': str(value), 'type': 'markdown'}
for column, value in row.items()
} for row in df_moby_dick.to_dict('rows')
],
tooltip_duration=None
)Let's comment on this issue if we change this example and/or provide an alternative.
